RAY KELLY, OF KNOBNOSTER, MISSOURI.

ROTARY ENGINE.

To all 107mm. it may concern Be it known that L'RAY KnLLY, citizen ofthe United States, residing at Knobnoster, in the county of Johnson andState of Missouri, have invented certain new and useful Improvements inRotary Engines; and I do declare the following to be a full,

' clear, and exact description of the invention,

such as will'enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which form apart of this specification.

,My invention relates to rotary engines, and more particularly to adevice of that type wherein a;constant volume of fluid is delivered to arotary member in order to drive said member and mechanism which may beconnected therewith.

It is theobject of the present invention to provide a. device ofthistype wherein fluid medium is delivered against opposite faces of therotary member and in a manner to exert a pressure on opposite facesofsaid member, which will tend to revolve same but will press equallyagainst the opposite faces, in order to obviate transverse thrustthereon.

It is also an object of the invention to provide the engine with arotarymember having a weighted rim for carrying momentum and therebyinduce steady travel of the member.

More particularly my engine consists of a rotary member having blades onits'opposite faces and extending in spiraled paths from the center ofeach face, together with a casing, the inclosing sides of which areprovided with spiral blades that radiate from the centers similarly, butin opposite directions, to the blades on the adjacent faces of therotary member, so that when the fiuid'medium' isadmitted between thefaces of the wheel and casing sides pressure against the blades of therotary member will tend to revolve said member and thereby produce thedesired motive power. In accomplishing the above noted objects I haveprovided improved details of struc are, the preferred form of which isillusrangement being such, however, that sages or channels 12 are leftbetween-the Specification of Letters Patent.

Fig. III is a transverse vertical section on thelineIIL-IILFig; I. Fig. IV is a side elevation of the rotary member.Fig. V isa side elevation of one of the inclosiug sides of the casing. I

Referring more in detail to the partsz- 1 designates a base orfoundation upon which the engine is mounted and 2 a case which ismounted on the base 1 and adapted for inclosing the working parts of theen'- gine. The case 2 comprises separate side members 3, preferably ofcast metal, and having bases 1 which are spaced apart to form a solidfoundation for supporting a rotary member and its shafting.

Above its bases 4 each side member comprises a circular concave 5, thecentral or hub part of which is extended laterally be drawings,

tween the vertical plane of the base 4 and provided with ajournaledbearing (i and a downwardl directed port 7, the concaves onopposite members being in circu1nferential alinement so that their baseportions are in close proximity and the bearings (i in tranversealinement.

Journaled in the bearing 6, in opposite sides of the engine casing, 18 ashaft 8, the

ends of which project beyond the casing in order to connect with powertransmitting mechanism (not shown), and-fixed on said shaft within thecasing is a rotary member 9. The member 9 comprises a hub part,preferablyelongated in, order to se cure a firm bearing on the shaft andto carry out the configuration of the fluid passage presently described.

The rotary member, of wheel 9 is of substantial Width at its rim l0, andopposite faces of the wheel are concaved to form the annular chambers 11into which the concave parts 5 of the casing sides'project, thearpassurfaces of the concave-convex rotary memher and easing.

On the rotary member 9' are blades 13 which extend in spiraled pathsfrom the ends of'the hub parts of the rotary member to the edge of theperiphery thereof through the channels 12, and on the convex faces ofthe casing sides are blades 14 which extend in spiraled paths throughoutthe convex surfaces of said sides but oppositely to the rotary blades13, so that the stationary and movable blades cross and provide rapidlywidening expansion chambers for a fluid medium when the engine isinoperation, it being apparent that as the blades cross each other theexpansion chambers increase in area very rapidly from the center out'Wardly.

Fixed to the peripheral edges of the concave portions 5 of the casingsides is a rim hood 16 which is spaced from the sidesto form aperipheral exhaust chamber 17 whlch is of greatest area at the bottom ofthe en-- gine Where it communicates with a relic conduit 18.

19 designates feed pipes which lead from any source of supply, such as aboiler, to the intake port 7 of the engine casing, the pipes being ofthe same diameter so that equal amounts of steam will be delivered toopposite sides of the casing in order to balance the rotary engine andthereby avoid transverse thrust which might tend to jam the parts andwould, in any event, produce friction suflicient to interfere to someextent with proper operation.

In using the engine, presuming the parts *to be constructed andassembled as described,

steam entering the casing through conduits 19 is delivered into theannular chambers 11 over the curved surfaces of the rotary member andcasing concaves and immediately between the inner ends of thespiraledblades 1314. As the steam enters the passage its expansionexerts pressure on the blades which tends to move the blades oneffecting a steady and even driving action on the rotary member. As thesteam expands and loses its driving force it escapes. through theenlarged exit port into the exv haust chamber 17, from which it escapesthrough the outlet conduits 18, so that there is no tendency of steam toaccumulate in the exhaust chamber and thereby interfere yyith theforward portion of the rotary mem- Having thus described my invention,what I claim as new therein, and desire to secure by L'etters-Patent, is

A rotary engine comprising a station-'- ary casing, a rotary memberinclosed within the casing and spaced-therefrom to provide passagesalong its opposite faces, oppositely directed spiraled plates on saidcasing, a rotary member, and means for delivering fluid under pressureinto the interior of the casing from opposite sides thereof.

2. A rotary engine comprising a stationary casing, a rotary memberinclosed w thin the casing and spaced therefrom to provide passagesalong its opposite faces, oppositely directed, spiraled plates on saidcasing, a rotary member diverging from the hubs of said parts, and meansfor simul-.
